Just built a new rig consisting of 3700x and rx 5700xt.
I install a fresh Arch. Got navi card to work with latest linux-mainline and last months amd-blobs and mesa-git.
Plays games superbly.

Okay I thought, so I went and treated myself even further and bought a Vive.
Installed SteamVR. Then when I try to launch it does one of two things.
It either freezes and crashes my system or launches into VrHome but with major graphics problems.
I have even tried the official amd driver. Same effect.

So my hope is someone out there has got passed this issue or do I have to wait for newer mesa?
